The eMotor that powers the Nissan LEAF is currently assembled in Japan. Soon, however, it will be produced in Decherd, Tenn., about 70 miles (110km) away from where the automaker will build the 2013 version of the electric car.

The partnership between the Renault-Nissan Alliance and Daimler reached a milestone last May when Tennessee officials joined Nissan leadership to break ground on a new manufacturing facility in Decherd, Tennessee.

Nissan has presented at CEATEC since 2007. But this year's attendance of three automakers at Japan's largest event showcasing electronics and IT, establishes cars as the newest - and biggest - of consumer electronics.
